The maximum likelihood (ML) Phylogenetic analysis of NBS-encoding genes from P. bretschneideri and P. communis. The phylogenetic tree was obtained using the IQ-TREE software on the basis of amino-acid sequences of NBS-encoding genes with ultrafast bootstrap 1000. ① Two subfamilies are shown. Red represents non-TIR group and Blue represents TIR group. ② The six classes of NBS-encoding genes are marked by different colors. Green means CC-NBS-LRR type, light yellow means TIR-NBS-LRR type, yellow means NBS type, light blue means TIR-NBS type, orange means CC-NBS type and purple means NBS-LRR type. ③ Domains of NB-ARC, LRR and TIR are displayed on the tree (CC domain was not shown), yellow means TIR domain, red means NB-ARC domain and blue means LRR domain
